  • Patent number: 6007312
    Abstract: An encapsulated magnet assembly has a magnet encapsulated during a two-step molding process. The first step includes molding a first molded section over a magnet assembly. The second step of the process includes molding a second molded section over the magnet and the first molded section in such a manner that the entire magnet is covered by the two molded sections completely. A first parting line is defined between the first and second molded sections along an elongate tapered section of the first molded section at the one end of the assembly. A second parting line is defined between the first and second molded sections at a dovetail on the first molded section. An outwardly tapered surface is provided on the dovetail. The two parting lines define leak-free seams between the two molded sections thereby sealingly encapsulating the magnet within the two molded sections.
